Before I retired, I used to get up at 4 to leave at 5 to be at work at 6. A little over 7 years, closer to 8. Would work 9 or 10 hours and my total time away from home was anywhere from 11 to 12 hours. On the days I played racquetball, it was 13 or 14. I can’t think of anything with 15 so I’ll stop now.
